Tied in my recent Android flick gesture addition to a Scroll() function. GameState now has a virtual function OnScroll() call that, by default is a no-op; each game state can choose to override how to respond to flick gestures. I've added one such override in the Deck Editor so that a flick up/down acts like the psp button up/down for scrolling between color filters.
